Groves insists that he is better prepared to go the distance this time.
George Groves has predicted that he will knock Carl Froch out in the third round, although his trainer, Paddy Fitzpatrick, thinks it will last till the fifth.
The British pair meet in their highly-anticipated rematch at Wembley on May 31, and the 25-year-old Londoner remains confident that he will be able to claim a clinical win this time round.
Following on from the controversy of the first fight in which many believed it was stopped prematurely, Froch has stayed out of the limelight and focused on the clash whilst appearing calmer in TV appearances and at press conferences.
In contrast, Groves has been as vocal as he was ahead of the first battle, and is seemingly ready to claim the world titles a week on Saturday regardless of who the referee is after Jack Reiss is expected to be replaced.
“I can’t see it going longer than three rounds, but Paddy Fitzpatrick thinks Carl will last until the fifth,” he said.
“I guess it depends on how Froch approaches it. He may try to take it as long as possible in the false belief that I will blow up in the later rounds.”
Groves insists that he is in much better physical condition and has been going 15-20 rounds in sparring with no problems, and as a result he hopes to dispel the myth that he is both ‘chinny’ and short on stamina.
Meanwhile, the challenger also believes that he could beat every other super middleweight in the world, including Andre Ward, although he conceded that that would be a tougher fight for him than facing Froch.
